DESCRIPTION：

 

The SCT2361 is a high efficiency synchronous step-down DC-DC converter integrated with a 3.3V, 150mA LDO. With the wide 4V-28V input voltage range and adjustable output voltage down to 0.6V, the SCT2361 supplies continuous 6A output current. The device fully integrates high-side and low-side power MOSFETs with 36mΩ/16mΩ on-resistance to minimize the conduction loss. The Supply of integrated 3.3V output LDO has path management between Vin and DC-DC converter output to achieve the lower power loss and better thermal performance.  
The SCT2361 adopts a Constant On-Time (COT) control to provide fast transient response and easy loop stabilization.  The device offers fixed 1ms soft start to prevent inrush current during the startup of output voltage ramping. Power Good with open drain output signals that the output voltage is within regulation.
The SCT2361 has the MODE pin to select Pulse Frequency Modulation (PFM) operation mode to achieve the light load power save, or Ultrasonic Mode (USM) to keep the switching frequency above audible frequency areas during light-load or no-load conditions, or the PWM mode to achieve the small output ripple.
Full protection includes over current protection, under-voltage protection, and thermal shutdown.
The converter requires a minimum number of external components and is available in a QFN- 12 (3mmx3mm) package.
